Title: Synchronous/asynchronous transfer system for field memory
Inventor: INOUE TAKESHI
IPC: G11C11/401
Filed: 1989-03-14
Abstract: PURPOSE:To obtain consecutive data by providing a generating section for next transfer signal and a transfer release signal and a synchronizing mode recognition section and controlling the transfer with a signal generated based on the outputs. CONSTITUTION:When a new transfer request signal is inputted during the transfer period, a succeeding transfer signal memory section 1 generates and prepares a required succeeding transfer depending whether an input signal is in the read mode or the write mode. When a write transfer request signal and a read transfer request signal are overlapped in time, a synchronizing mode recognition section 2 recognizes the mode to be the synchronizing mode and outputs a synchronizing signal Sync. After the end of transfer, the mode is released with a signal from a transfer release signal section 3. After the end of transfer of a transfer signal, based on a transfer request from the generating sections 1 - 3, a signal controlling the transfer between a memory block bit line and a read/write register is prepared. Even when the clock outputted from the recognition section 2 is operated synchronously or asynchronously, consecutive data is maintained.

Title: Semiconductor device
Inventor: OHORI TATSUYA
IPC: H01L29/778
Filed: 1987-03-18
Abstract: PURPOSE:To improve the performance of a high electron-mobility FET by forming the hetero-junction of an InGaAs layer and an InGaP layer, to which an impurity is doped, and using the InGaAs layer as the channel of interface- quantized carriers. CONSTITUTION:An AlGaAs buffer layer 2, an InGaAs layer 3, an InGaP electron supply layer 4 and a GaAs layer 5 are shaped onto a semi-insulating GaAs substrate 1. Source-drain electrodes 8 are patterned onto the layer by employing AuGe/Au, etc., and alloy regions 8A are formed in depth reaching the layer 3 through heat treatment. A gate electrode 9 is shaped onto the layer 5. According to such constitution, the surface concentration of a two-dimensional electron gas is increased by the hetero-junction of the layer 3 and the layer 4. Since the electrode 9 is formed onto the layer 5, the large height of a Schottky barrier is acquired, thus improving performance.

Title: Semiconductor photodetector
Inventor: MIZUOCHI HITOSHI
IPC: H01L31/10
Filed: 1989-03-14
Abstract: PURPOSE:To make it possible to separate and drift carriers generated in a depletion layer efficiently by providing an InGaAs layer on an SiN surface protecting film by MOCVD, MBE and the like, and absorbing light, which is not projected on a light receiving surface, in said InGaAs layer. CONSTITUTION:A semiconductor photodetector has an SiN surface protecting film (AR coat) 9a, an SiN surface protecting film 9b which is an HR coat and In1-xGaxAs (x<=0.53) light absorbing region 10. Light which is inputted from a part other than a light receiving surface is not reflected with the AR coat 9a but reaches a light absorbing region 10. Since the forbidden band width of the region is smaller than the incident light, the light is absorbed. The lower side of the light absorbing region comprises the HR coat 9b, and the light cannot enter into a crystal. The outer surface of the light absorbing region 10 is shielded with the SiN surface protecting films, and the light is not transduced into current. Therefore, the light enters the crystal only through the light receiving surface. The light is absorbed in an In0.47Ga0.53As light absorbing layer 3. Carriers can be separated and drifted in a depletion layer efficiently.

Title: Numeral transmission processing system
Inventor: MORITOMO HARUO
IPC: H04Q3/545
Filed: 1983-04-12
Abstract: PURPOSE:To transmit a numeral without deterioration pulse transmission precision by equalizing the periods of a dial pulse fall control program DPON and a dial pulse rise control program DROFF in an electronic exchange and making different start times of them from each other. CONSTITUTION:When a received dial numeral is trasmitted to a trunk for outgoing connection, a transmission number setting program SEND extracts trunk information TKNO of the other party on a transaction memory B of a pertinent call and a received numeral DS and sets them to a trunk memory T. With respect to pulse generation, for example, programs DPOFF and DPON are driven at periods of 96ms, but the program DPON is started 32ms after the program DPOFF. That is, the programs DPON and DPOFF are started with a shift of 32ms so that the time of make of the pulse is 32ms, and the program DPOFF controls the pulse to change it from turn-off to turn-on, and the program DPON controls the pulse to change it from turn-on to turn-off. Thus, break and make signals are generated. This signal conversion is performed by writing programs DPOFF and DPON in a transmission signal memory SSM having a hard interface.

Title: Fuel injection control method for internal combustion engine
Inventor: MIYAGI HIDEO
IPC: F02B75/18
Filed: 1981-04-30
Abstract: PURPOSE:To eliminate the internal EGR, stabilize the combustion, and improve the specific fuel consumption by dividing all cylinders into odd cylinder groups each of which having the same number of cylinders and by stopping the fuel injection into the following cylinder group in succession to the preceding cylinder group. CONSTITUTION:All cylinders of an internal combustion engine are divided into odd cylinder groups each of which having the same number of cylinders, and the fuel is injected into individual cylinder groups every time the engine revolves for a predetermined crank angle. Whether the fuel is injected or not into individual cylinder groups is controlled by whether load signals are sent out or not from the CPU 20 through control lines 63, 68, 74. If the injection is stopped into the following cylinder group after the fuel has been injected into the preceding cylinder group, the explosion would not occur for the same cylinder group in the preceding explosion stroke, resulting in no internal EGR generated. Thereby, the combustion is stabilized, the running characteristics is extensively improved, and the specific fuel consumption is also improved remarkably.
